Ligand Definition. A ligand is an atom, ion, or molecule that donates or shares one or more of its electrons through a covalent bond with a central atom or ion. It is a complexing group in coordination chemistry that stabilizes the central atom and determines it reactivity.
In coordination chemistry, a ligand (/lÉªÉ¡Énd/) is an ion or molecule (functional group) that binds to a central metal atom to form a coordination complex.The bonding between metal and ligand generally involves formal donation of one or more of the ligand's electron pairs.DTA 4â , when it is hexidentate, binds as a Îº 6 -ligand, the amines and the carboxylate oxygen atoms are not contiguous. In practice, the n value of a ligand is not indicated explicitly but rather assumed. The binding affinity of a chelating system depends on the chelating angle or bite angle.
